Failure cases.
We also share failure cases which could be helpful for other researchers. For every experiment, we give the results approximately compared to baseline JPoSE [1]}. 1) If we implement self-attention to the textual features as it is done to the video features, the results decrease around 2-3%. 2) When we increase the batch size or embedding size, the results decrease 1-2%. 3) We get 1-2% lower results when applying temporal max-pooling rather than mean pooling.
